SQL Server 2000 - Need help to write the query

I need help to write a query. The details of which is given below

employee table

Empid EmpName EcatID ProjectID
1200 Rama 5 2
1201 Shiva 5 2
1202 arab 6 44
1207 Kumar 3 28
1208 Despande 6 2
1210 Divya 3 50
1230 praveen 1 44
1232 Raghu 1 28 1247 sumitra 1 2
1266 Manoj 1 39
1274 Siddu 2 39

Empskill Table

EmpID CourseID SelfRating Evalrating
1201 10 4 -
1202 11 8 7
1202 100 8 -
1200 12 7 7
1207 99 10 9
1207 100 10 8
1207 101 8 8
1207 102 5 5
1207 103 6 4
1207 104 4 4
1274 104 8 8

Result Needed:

Empid PMName No Of Subordinates TotalNoofSubjsratedbysubords TotalNoOfEvalRating

1230 praveen 1 2 1
1232 Raghu 1 6 6
1247 sumitra 2 2 1
1266 Manoj 1 1 1

EcatID =1 means he is a Project Manager
a PM has a ProjectID, his sub-ordinates have the same ProjectID (thats how you locate them)

Thanks
Have a nice day

FROM employee t1
INNER JOIN employee t2

INNER JOIN Empskill t3
ON t3.EmpID=t2.EmpID
